System Integration - Gpio Connector - Christie M Series User Manual

Section 2: Installation and Setup
For example, you may want to use both an RS-422 compatible controller and an Ethernet connected PC for
working with a network of projectors linked via their RS-232 IN/OUT ports.
To isolate just RS-422 communications, select RS-232 and Ethernet Joined. Only projector 1 will respond to
the RS-422 controller.
To isolate just Ethernet communications, select RS-232 and RS-422 Joined. Only projector 1 will respond via
Ethernet.

2.9.9 System Integration - GPIO Connector

The GPIO connector located on the input panel provides a flexible method of interfacing a wide range of
external I/O devices to the projector. There are 7 GPIO pins available on the 9pin D-Sub GPIO connector,
which are configurable via RS-232 commands. The other two pins are reserved for ground and power - see
table below for pin identification.
NOTE: The serial cable required for connecting the external device to the projector's GPIO connector, must
be compatible with the external device.
